Abstract (en)
[origin: US2012327153A1] The present invention is directed to an apparatus and method for determining and adjusting printhead pressure of a thermal printer. The apparatus includes a printhead support housing operable for placement in a print station of a printer. A motor housed within the printhead support housing and being operable for driving a plurality of synchronized rotating gears, the gears being mounted about posts wherein the posts are configured to cause the gears to compress or decompress a set of biasing mechanisms mounted below the gears and connected to the printhead. A sensor unit operable for monitoring the thickness of a print media and in communication with a control circuit operable for adjusting the printhead pressure being applied to the print media during a print operation, wherein the printhead pressure corresponds to a pre-defined level relative to the thickness of the print media.
